回复: BUG #17454: Using psql without ipv4 address,the inet_server_port do not return PORT.

If I run multiple instances on one server with local socket, how can I distinguish them?I think the port is need.

Bug reference: 17454
Logged by: Laowu wong
Email address: thbytwo(at)live(dot)cn<mailto:thbytwo(at)live(dot)cn>
PostgreSQL version: 14.2
Operating system: centos 7
Description:

It should return the server port when I execute 'select inet_server_port();'
with the command line 'psql -p 15431'.
It seems that if I do not enter the ipv4 address in the
psql-command-line,the pg will return null.

Right, because the default is to use a local socket.
